Abstract

fetched live from OpenAlex

In this work, we implement a Dynamic Programming (DP) algorithm for Sequence Comparison (SC) purposes. We aimed at obtaining a better compromise between the processing acceleration optimization and the hardware cost. A simplified Edit Distance (ED) calculation formula is used, where we introduce two new simplified logical equations based on this last formula. A Systolic Array (SA) based on our simplified Processing Element (PE) can compare sequences with a great length and a high processing frequency. Our system speed-up shows a gain varying between 13% and 142% compared to other systems, according to the considered FPGA family.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
